Major haemorrhage is a leading cause of mortality following major trauma. Increasingly, Helicopter Emergency Medical Services (HEMS) in the United Kingdom provide pre-hospital transfusion with blood products. The study here compares mortality for patients with suspected traumatic haemorrhage transfused with pre-hospital packed red blood cells (PRBC) compared to crystalloid.

In this single-centre UK HEMS study, patients with the suspected traumatic haemorrhage who received a PRBC transfusion between 1 January 2010 and 1 February 2015 were observed. Patients receiving pre-hospital PRBC were significantly less likely to need an

in-hospital major transfusion compared to those receiving pre-hospital crystalloid. Early haemorrhagic death comprises a notable proportion of patients who may benefit from early transfusion.


The ˚M Warmer System is portable blood and IV fluid warming device designed for optimal pre-hospital use as it is small and lightweight as well as has extremely efficient warming capabilities (150 ml/min). Read more about the ˚M Warmer System here.
